Work you can account for.

The surface where work is planned, carried out and accounted for, with the evidence kept beside the change that produced it.

Thinking, made checkable.

An editor for prose and for structured text, where what you are saying and how it is shaped stay legible at the same time.

Numbers that show their working.

Spreadsheets that keep their reasoning, so that any figure can be followed back to whatever it was derived from.

What you owe, and when.

A place to keep what you have actually undertaken, so that a duty and a passing wish never end up looking alike.

Effort, plainly recorded.

A plain record of physical effort, kept without turning the body into a scoreboard to be beaten.

A word is a tool.

Vocabulary learned at the rate it is genuinely retained, rather than the rate at which it can be crammed.

Practice, kept honest.

For practising an instrument, and for keeping an unflattering record of the hours that went into it.

Fluency before the machine.

Arithmetic and mathematics practised until they are fluent, so the machine stays a convenience rather than a crutch.
